Explanation:
1 mile = 1609m
Distance=260 miles= 418340 m
Speed= 40 m/s
Time = distance/speed
= 418340/40
=10458.5 seconds
= 2.9 hours

Answer:
4 A
Explanation:
V = IR, where V=voltage, I=current, R=resistance. This is Ohm's Law. (remember that for units V = volts, Ω = ohms, A = amperes.)
V = IR
12 V = I * 3 Ω
12/3 = I
<u>I = 4 A</u>
